           Summary: take(map) problem
           Product: D
           Version: D2
          Platform: Other
        OS/Version: Windows
            Status: NEW
          Keywords: wrong-code
          Severity: normal
          Priority: P2
         Component: Phobos
        AssignedTo: nobody puremagic.com
        ReportedBy: bearophile_hugs eml.cc



D2 code:


import std.stdio, std.algorithm, std.range;
auto foo(int p) {
    return map!((int n){ return p; })(iota(3));
}
void main() {
    writeln(take(foo(2), 20));
}


To me it prints:
[4221068, 4221068, 4221068]

A comment by Daniel Murphy:

 The problem is the parameter p is not being heap allocated.  I'm fairly sure
 it's already in bugzilla, something about failing to detect escaping
 references with alias parameters.

This bug appears to be fixed in latest git HEAD (and probably last release as
well)? Bearophile, could you re-test this against the latest release and close
the bug if it doesn't happen anymore?

Works for me for as far back as at least 2.061. I'll close it.
